I have an expertise in a certain line of work. I am sure this line of work would support some apps. I am sure people would pay for them. I can design them, and how I would like them to work as I am in the field. However I have no idea how to build them.
How do I go about to have some apps built ?
What platform are you interested in?
Apps (generally being small and on very modern systems) are a pretty gentle introduction to programming, and there are a bunch of books out there on doing it. So I’d say write it yourself.
Otherwise, you get the standard “ideas are worth nothing without implementation,” line, I’m afraid. Convince a programmer to help you out and split the proceeds, or hire one at prevailing wage and keep the proceeds yourself.
